In this episode we dive into Chapter 3 of Applied Behavior Analysis in Early Childhood Education: An Introduction to Evidence-Based Interventions and Teaching Strategies (Second Edition, 2024) by Laura Baylot Casey and Stacy L. Carter. This chapter focuses on supporting communication in the early years, exploring how theory, assessment, intervention, and technology all intersect to give children a voice.

We begin by reviewing major perspectives on language development—nativist, constructivist, and behaviorist—and highlight Skinner’s analysis of verbal operants as a foundation for ABA interventions. The discussion then turns to receptive and expressive language development, social nuances like joint attention, and the urgency of early intervention under IDEA. We cover key assessments such as the ASQ-3, ELM Scale-2, LDS, VB-MAPP, and ABLLS-R, before moving into evidence-based interventions like PECS, teaching joint attention, and enhanced milieu teaching. The chapter also explores the expanding role of augmentative and alternative communication (AAC), from low-tech picture systems to advanced voice-output devices and AI-driven tools. By grounding communication support in ABA principles and early intensive intervention, educators and practitioners can profoundly empower children to express themselves, build social connections, and lay the foundation for lifelong learning.

Happy listening, and let’s keep diving deep into the world of ABA!
